Charge Timer
The charge timer starts once battery voltage goes above the float voltage by a certain amount. The timer will run for
a pre-determined amount of time based on the battery specifications provided by the manufacturer, but is adjustable
in the PowerWizard software. When the timer expires, the charger will switch into float mode. A new timer will start
and the charger will not return to bulk or absorption mode for a predetermined amount of time to allow the battery to
recover.
Battery Maintenance
Maintain the batteries in your battery storage system according to the battery manufacturer’s recommendations. In
particular, monitor the water level in the batteries as described on the previous page.
Battery Temperature Sensor
A Battery Temperature Sensor (BTS) is included with the SolarMax charge controller. Battery temperature affects
the ideal charging voltage, the cooler the battery temperature the higher the ideal charging voltage. SolarMax, with
a properly installed BTS, will protect the batteries from overcharging by adjusting the charging voltage to match the
battery temperature. One of the setup values in PowerWizard is the Battery Temperature Coefficient. This value should
be supplied by the battery manufacturer and used during setup. There is no need to use a minus sign when entering the
coefficient. The coefficient is the value recommended by the manufacturer times the number of batteries in series.
The BTS should be firmly attached to a battery in a central part of the pack by double sided tape, either on the side or
on the top of the battery
